WEATHER STRIP.

Application filed March 23, 1926. Serial No. 96,750.

The invention relates to weather strips for use in connection with window frames and sash, and has for its object to provide a device of this character comprising a body portion formed from spring material and interposed between the side of a sash and the window j amb and having its marginal edge secured to the window j amb beneath the inside strip and its outer edge provided with a right angularly disposed flange interposed between the outer side of the sash and the parting strip and provided with an inwardly extending bead forming a vertically disposed rib slidablymounted in a channeled member disposed in a rabbet in the outer side of the sash, thereby forming a water tight joint.

A further object is to provide members carried by the sash preferably adjacent its upper and lower end and having convexed surfaces and members carried by the jamb beneath the inside strip and having convex surfaces cooperating with the convexed members carried by the sash when the sash is raised or lowered and forming means for forcing the sash outwardly and maintaining a close engagement between the rib carried by the spring member and the channeled member carried by the sash.

WVith the above and other objects in view the invention resides in the combination and arrangements of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing:

Figure 1 is a horizontal sectional view through a window jamb and a portion of a sash, showing the weather strip applied thereto.

Figure 2 is a perspective view of the weather strip.

Figure 3 is a perspective view of the convexed members.

Figure 4 is a vertical transverse sectional view through the lower end of a sash and a window sill showing a modified form of weather strip.

Figure 5 is a perspective view of the weather strip members shown in Figure 4 and showing the same in position to engage each other.

Referring to the drawing, the numeral 1 designates a window jamb, 2 an inside strip secured thereto and 3 the parting strip. Slidably mounted between the strips 2 and 3 is a sash 4.

Disposed between the side of the sash 4 and t e window jamb 1 is a spring plate 5, which spring plate is provided with an angularly disposed flange 6, which is secured to the jamb 1, and it will be noted. the plate 5 inclines outwardly away from the jamb 1, and terminates adjacent the parting strip 3, and the outer side of the sash 4. Spring plate 5 is provided with an angularly disposed flange 7,'which overlies the outer side 8 of the sash 4 between the sash and the parting strip 3, and is rovided with a vertically disposed rib 9, wliich extends inwardly and is slidably mounted in a vertically disposed channel 10 dis osed in a rabbet 11 in the outer face 8 of t 1e sash thereby preventing a bulky structure. The channeled member 10 is provided with a flange 12 which is secured to the outer side of the sash 4. It will be seen as the sash 4 ismoved upwardly or downwardly a positive sliding connection will be maintained between the rib 9 and the channeled member 10 which will prevent air or water from being driven around the side of the sash. To insure a positive engagement of the rib 9 and the channel 10 when the sash is in lowered position, the sash is provided with convexed plates 13 which are carried by piercing members 14, and which convexed plates cooperate with the convexed surfaces 15 carried by the plates 16. The plates 16 are disposed in the channel 17 of the inside strip 2, and are held in place by means of screws 18. However when first applying the plates 16, nails 19 are passed through the apertures 20 of the plates 16 for holding the same in proper position until the screws 18 are driven.

From the above it will be seen that a weather strip is provided for window sash and frames which is positive in its operation, may be easily and quickly applied to a window frame and sash and will positively exclude the weather. It will also be seen that the convexed members 13 and 15 when in engagmeent will force the sash outwardly thereby insuring a positive close sliding engagement between the rib 9 and the channel 10.

Referring to Figures 4 and 5 wherein a modified form is shown, the operation is substantially the same with the exception that it isv applied to the lower end of the sash d, and in which form the outer edge of the plate 5" terminates in an upwardly extending head 5 which engages the horizontal portion 5 of the channeled member 5 and which channeled member is disposed in a channel 5 in the under side of i the sash i. It will be noted the spring plate 5 inclines upwardly and outwardly, and when the sash 4 is moved downwardly, there will be a tensioned engagement be tween the upwardly extending head 5? and the portion 5 of the channeled member, thereby insuring a water tight connection.

The invention having been set forth what is claimed as new and useful is r A weather strip for slidable sash slidably mounted between strips and adjacenta jamb, said weather strip comprising a plate secured to the jamb and including outwardly and terminating adjacent the outer side of the sash, a flange carried by the outer end of the plate and overlying the outer side of the sash, a channeled member carried by the outer side of the sash, a bead carried by the flange carried by the plate and disposed in the channeled member of the sash, convexed members carried by the inner side of the sash, plates secured to the jamb beneath one of the strips and con vexed members carried by said plates and cooperating with the converted members carried by the sash and forming. means whereby the sash will be forced outwardly in parallel relation to the strips.

In testimony whereof I hereunto afliX my signature.
